Coinsurance, Deductible, and Replacement Cost Holdback
North Fork Mill owns a commercial building with a replacement cost of $2,000,000. Its property policy has a building limit of $1,200,000, an 80% coinsurance clause, a $10,000 deductible, and replacement-cost valuation. A fire causes $400,000 in replacement-cost damage; depreciation on the damaged property is $100,000. North Fork's public adjuster prepares a claim for the full $400,000 and tells the owner that the deductible will be subtracted only once, after coinsurance, and that the insurer must pay the full limit because the loss is large. The insurer instead applies the coinsurance penalty and offers an actual-cash-value first payment. The owner wants to know why the policy limit was not paid, how the penalty is calculated, and what happens to the depreciation holdback if the building is repaired. The adjuster also must advise whether the $40,000 already spent on temporary repairs changes the coinsurance calculation.
1. Calculate the coinsurance penalty and the initial payment on both a replacement-cost and an actual-cash-value basis.

Coinsurance is tested against the limit that should have been carried, not the loss. Required insurance = 80% x $2,000,000 = $1,600,000. Carried = $1,200,000. Ratio = $1,200,000 / $1,600,000 = 0.75. The RCV loss is $400,000, so the coinsurance-adjusted loss is $400,000 x 0.75 = $300,000. Subtract the $10,000 deductible once: $290,000 payable on a replacement-cost basis. If the insurer pays ACV first, ACV loss = $400,000 - $100,000 = $300,000; $300,000 x 0.75 = $225,000; less $10,000 = $215,000. The remaining $75,000 of depreciation ($100,000 x 0.75) is held back until repairs are completed.
2. Explain why the insurer does not owe the full $1,200,000 policy limit.

The limit is not a target. The policy pays the covered loss after applying valuation and coinsurance, capped by the limit. Here the adjusted loss of $300,000 is well below the $1,200,000 limit, so the limit does not set the payment. The owner was underinsured: carrying $1,200,000 against a $1,600,000 requirement produced a 25% penalty. The insurer owes $290,000 on an RCV basis, not $1,200,000. If the loss had exceeded the limit and the coinsurance requirement had been met, the limit would cap recovery.
3. How should the $40,000 in temporary repairs be treated in the coinsurance calculation?
Read the worked answer
The $40,000 temporary repairs are part of the covered loss if the policy covers them, but they do not change the coinsurance ratio because the ratio uses the policy limit, not the amount spent. The adjuster should include the temporary repairs in the total loss and avoid double-counting them in the permanent repair estimate. The same 0.75 factor and one deductible apply to the total covered loss, unless the policy provides separate coverage or a separate deductible. The adjuster should document invoices and photos and present the calculation to the insurer in writing.
